[0002] The electric pick is a commonly used electric tool, usually used for hammering and chiseling on the ground. In the actual hammering and chiseling process, the electric pick needs to be moved synchronously. Then the electric pick will be placed on a movable cart for operation, which is convenient for transferring the construction area at any time. The existing electric pick locomotives usually include a bracket, on which a lock for fixing the electric pick is provided; the bottom of the bracket is provided with rollers for movement, and the top of the bracket is provided with a handle for pushing. In actual work, it is usually necessary to adjust the impact angle of the electric pick. The existing cart can only push the bracket manually to change the impact angle between the electric pick and the ground. The degree of automation is low and it is relatively laborious. At the same time, the height of the handle cannot be adaptively adjusted. Due to the different heights of different operators, the operator often cannot match the height when pushing the handle, and needs to bend down to push the bracket, which has poor versatility. Therefore, it is necessary to design an electric pick locomotive that is easy to adjust the working angle to overcome the above difficulties. Summary of the invention

[0006] In the default state, the locking device is in a locked state, at which point the end of the latch is inserted into the limiting hole, so that the support platform cannot rotate relative to the horizontal base, and the electric pick can stably maintain the corresponding impact angle. When the inclination angle of the support platform needs to be adjusted, the operator clamps the two push blocks with his hands, and the two push blocks synchronously drive the two latches to approach each other along the direction of the clearance holes; at this time, the reset spring is in a compressed state, and the latch will disengage from the limiting hole. After adjusting the angle of the support platform, align the guide tube with the limiting hole at the corresponding position, release the push block, and the latch will automatically extend into the corresponding limiting hole under the action of the reset spring.

[0013] In the default state, the lock teeth on the first locking seat and the lock teeth on the second locking seat are meshed with each other, so that the two cannot rotate relative to each other; because the first locking seat is buckled and installed on the vertical mounting bracket, and the first locking seat and the vertical mounting bracket cannot rotate relative to each other; in this way, the handle bracket cannot rotate relative to the vertical mounting bracket, and the handle body can be maintained at the corresponding height. When the tilt angle of the handle bracket needs to be adjusted, turn the rotary switch to move it away from the second locking seat, and then pull the second locking seat to disengage it from the first locking seat; then adjust the tilt angle of the handle bracket according to the actual use conditions, and then push the second locking seat to move it close to the first locking seat; when the lock teeth on the first locking seat and the lock teeth on the second locking seat are meshed with each other, turn the rotary switch in the opposite direction to lock the second locking seat, so that the handle bracket cannot rotate. Since a buffer is provided between the first locking seat and the vertical mounting bracket, the vibration amplitude of the second locking seat can be reduced by the buffer; when the electric pick is in impact operation, the operator has a better effect of holding the handle body, reduces the vibration, and provides a better user experience. By providing the first protrusion, the second protrusion and the first groove, the first locking seat and the second locking seat have better concentricity, the connection between the two is more stable, and the handle bracket can be reliably maintained at the corresponding tilt angle.
