Technical realization elements:

4. Therefore, the technical problem to be solved by the present utility model is to overcome the shortcomings of the lack of applicability of the mechanical arm in the prior art, thereby providing a mechanical arm, including:

5. Fixing device;

6. One end of the arm is rotatably connected with the fixing device;

7. No. 2 arm, one end is rotatably connected with the other end of the No. 1 arm, and the other end has a first channel along the axial direction of the No. 2 arm;

8. No. 3 arm, one end is slidably inserted in the first channel;

9. A telescopic device, which is detachably fixed on the second boom, and the driving end of the telescopic device is connected with the third boom for driving the third boom to slide back and forth in the first channel.

10. Preferably, the telescopic device includes a telescopic mechanism and a telescopic member connected to the telescopic mechanism, the telescopic mechanism is detachably fixed on the second boom, and the telescopic member is connected to the third boom Above, the telescopic mechanism is used to drive the telescopic member to slide back and forth in the axial direction parallel to the third boom.

11. Preferably, the telescopic mechanism includes a driver and a driving sleeve detachably fixed on the driver, the driving sleeve has a second channel along the axial direction of the driving sleeve, and the telescopic member is slidable The ground passes through the second channel.

12. Preferably, the fixing device is provided with a first driving device, and the driving end of the first driving device is fixedly connected with one end of the first arm to drive the first arm on the fixing device Rotate.

13. Preferably, it further comprises a rotating connecting piece, a second driving device is further provided on the fixing device, and the driving end of the second driving device is fixedly connected to one end of the rotating connecting piece. The other end is fixedly connected with the rotating shaft, and the other end of the first arm is rotatingly connected with the rotating shaft.

14. Preferably, the rotating connecting member includes a first rotating member, a second rotating member, and a transmission member connecting the first rotating member and the second rotating member;

15. The driving end of the second driving device is connected with the first rotating member, and the rotating shaft is fixedly connected with the second rotating member.

16. Preferably, one end of the second arm is provided with a fixing part, two opposite sides of the fixing part are extended with fixing parts, and the two oppositely arranged fixing parts are fixed at the opposite ends of the rotating shaft.

17. Preferably, a first adjuster is connected to the other end of the third arm, and the first adjuster includes a first U-shaped support, a third driving device, and a second U-shaped support that are connected in turn;

18. The first U-shaped support is connected to an end of the third arm away from the second arm, and the second U-shaped support is connected with equipment.

19. Preferably, a second adjuster is connected to the end of the third arm away from the second arm, and the device is connected to the first adjuster through the second adjuster, and the second adjuster is connected to the The first adjuster is cross-connected;

20. The second adjuster includes a third U-shaped support, a fourth driving device, and a fourth U-shaped support that are rotatably connected in sequence, and the third U-shaped support crosses the second U-shaped support connect.

21. Preferably, the first u-shaped support can rotate on the axis of the third arm as a self-rotating axis.

22. The technical solution of the utility model has the following advantages:

23.1. In the mechanical arm provided by this utility model, the telescopic device is detachably fixed on the second arm and the third boom. When the telescopic length of the third boom in the second boom needs to be changed, the telescopic device can be exchanged to change The telescopic device that meets the use requirements is replaced, so that the entire mechanical arm does not need to be replaced, which improves the applicability of the mechanical arm.

24.2. In the robot arm provided by the utility model, the first driving device and the second driving device are arranged on the fixing device. Compared with the second driving device arranged on the robot arm in order to promote the rotation of the second arm, the robot arm is reduced. The load to be borne when rotating makes the extension range of the mechanical arm larger.
