[0075] Figure 7 It is a perspective view of the clamping device in the mounting auxiliary according to the embodiment of the application.

[0076] Figure 8 It is a front view of the clamping device in the mounting auxiliary according to the embodiment of the application.

[0077] As Figures 7-8As shown, the clamping device 8 is mounted inside the frame body 9 below the locking shaft device 6; the clamping device 8 comprises a clamping mechanism 81, a pin shaft 82, and a second compression spring 83.

[0078] The clamping mechanism 81 corresponds to the position of the long gap of the first locking shaft 61, and the clamping mechanism 81 is provided with a shaft hole, the pin shaft 82 passes through the shaft hole of the clamping mechanism 81, and the two ends respectively extend into the pin shaft hole provided inside the frame body 9, and the position of the pin shaft hole inside the frame body 9 corresponds to the position of the shaft hole of the clamping mechanism 81.

[0079] The pin shaft 82 is fixed inside the frame body 9 by a plurality of jacks 821, that is, the clamping mechanism 81 can rotate a certain angle around the pin shaft 82 as the center;

[0080] The clamping mechanism 81 is provided with a downward blind hole for placing the second compression spring 83.

[0081] One end of the second compression spring 83 abuts against the blind hole of the clamping mechanism 81, and the other end abuts against the corresponding position inside the frame body 9. The second compression spring 83 is used to push the clamping mechanism 81 to rotate.

[0082] The frame body 9 is a main body, and the frame body 9 is provided with a switch lock mark 5 at both ends;

[0083] The frame body 9 comprises a cover plate 91 and a supporting mechanism 92.

[0084] The cover plate 91 cooperates with the groove provided at the top of the frame body 9 and is installed by screws.

[0085] The supporting mechanism 92 is located at the bottom of the frame body 9 and is an integral structure with the frame body 9. The supporting mechanism 92 is used to be connected with the ruler shell 2 and cooperates with the clamping mechanism 81 to realize the fixation of the installation auxiliary part 3 on the ruler shell 2.

[0086] The frame body 9 is provided with the same mechanical interface as the trolley device 1, which is used to simulate the connection between the trolley device 1 and the connecting piece 4.

[0087] The working principle of the installation auxiliary part provided by the application is as follows:

[0088] When the installation auxiliary part is in the initial state, that is, in the open state: the short gap of the first locking shaft 61 in the locking shaft device 6 faces the movable block 73 in the supporting device 7, and the linear shaft 74 is in

[0089] The free sliding state, that is, the unfixed state;

[0090] At this time, the inner hexagonal wrench is put into the inner hexagonal wrench hole on the locking shaft device 6, and the first locking shaft 61 and the second locking shaft 62 in the locking shaft device 6 are rotated as a whole by rotating the inner hexagonal wrench;

[0091] During the rotation: the cam mechanism on the first locking shaft 61 simultaneously exerts pressure on the back of the movable block 73 and the clamping mechanism 81.

[0092] When the movable block 73 is subjected to pressure, it moves towards the linear shaft 74, fixing the linear shaft 74; the first compression spring 72 pushes the linear shaft 74 and the sliding block 75 to move downward as a whole.

[0093] When the clamping mechanism 81 is subjected to pressure, it rotates around the pin shaft 82, i.e. one end of the clamping mechanism 81 moves towards the second compression spring 83, and the second compression spring 83 is compressed; the other end of the clamping mechanism 81 moves upward.

[0094] When the quarter-circle notch of the first locking shaft 61 abuts against the limiting pin 63, the locking shaft device 6 stops rotating.

[0095] At this time, the auxiliary component is in a locked state: the short notch of the first locking shaft 61 in the locking shaft device 6 faces the clamping mechanism 81 in the clamping device 8.

[0096] Then, by rotating the inner hexagonal wrench in the opposite direction, the pressure on the back of the movable block 73 and the clamping mechanism 81 disappears:

[0097] The movable block 73 resets towards the first locking shaft 61, and the extrusion force on the linear shaft 74 disappears, and the linear shaft 74 returns to a free sliding state.

[0098] The second compression spring 83 restores the deformation and pushes the clamping mechanism 81 to rotate in the opposite direction around the pin shaft 82 to reset, i.e. one end of the clamping mechanism 81 moves upward, and the other end of the clamping mechanism 81 moves downward.

[0099] Although the embodiments of the present application have been shown and described above, it should be understood that the above-described embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above-described embodiments within the scope of the present application.
