[0006] As a further description of the above technical solution:

[0007] The striking head is in a sealed shape.

[0008] As a further description of the above technical solution:

[0009] The limiting strip is in an arc shape.

[0010] As a further description of the above technical solution:

[0011] The portion of the limiting rod located outside the sleeve is provided with an external thread.

[0012] As a further description of the above technical solution:

[0013] The locking strip is rectangular.

[0014] As a further description of the above technical solution:

[0015] The length of the locking strip is 3-5 cm.

[0016] Compared with the prior art, the utility model provides a gear auxiliary installation device having the following features:

[0017] Beneficial effects:

[0018] 1. In the utility model, the striking head increases the contact surface with the hammer, and the gear pressing head increases the contact surface with the gear, making the striking safer and more stable;

[0019] 2. In the present invention, the position of the limit rod is moved according to the scale groove, and the downward movement distance of the sleeve is limited by adjusting the position of the limit rod. When the end of the gear mounting shaft contacts the limit rod, the downward movement of the sleeve will be stopped. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figure 1-Figure 3 The utility model provides a gear auxiliary installation device, including a sleeve 1, the upper end of the sleeve 1 is integrally connected to a knocking head 2, the lower end of the sleeve 1 is integrally connected to a gear pressing head 3, a movable through slot is penetrated through the sleeve 1, a scale slot 4 is provided on the side of the sleeve 1 located at the movable through slot, a limit strip 5 is provided on the outer side of the movable through slot, the limit strip 5 is fixedly connected to a limit rod 6, and the limit rod 6 passes through the movable through slot and is threadedly connected to a locking strip 7.

[0028] Specifically, Figure 1 As shown, the striking head 2 is sealed and the striking is safe.

[0029] Specifically, Figure 3 As shown, the limiting strip 5 is in an arc shape and can be in contact with the sleeve 1 .

[0030] Specifically, Figure 3 As shown, the portion of the limiting rod 6 located outside the sleeve 1 is provided with an external thread, the locking strip 7 is rectangular, the length of the locking strip 7 is 3-5 cm, and the manual operation is convenient.

[0031] Working principle:

[0032] When in use, according to the distance required for the gear to be knocked and moved, the position of the limit rod 6 is moved on the moving through slot, the scale groove 4 provides a reference for the movement, the position where the limit rod 6 stops is determined, the locking strip 7 is rotated to fix the position of the limit rod 6, the gear pressing head 3 is aligned with the installation sleeve, and the hammer hits the position of the knocking head 2 to knock the gear down and fix it. During the downward movement of the sleeve 1, the limit rod 6 contacts the installation shaft, and the sleeve 1 stops moving downward.
