[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] The following describes a spiral bevel gear provided by some embodiments of the present invention in conjunction with the accompanying drawings. Example 1

[0023] Combine Figure 1-4As shown, the utility model provides a spiral bevel gear, including a main body mechanism, a fixing mechanism and a locking mechanism. The main body mechanism includes a bevel gear 110, a rotating shaft 120 installed on the inner side of the bevel gear 110, an external shaft 130 sleeved on the rotating shaft 120, and a sliding groove 140 provided on the rotating shaft 120. The shape of the rotating shaft 120 is cross-shaped, and a cross-shaped through groove that fits the shape of the rotating shaft 120 is provided in the middle of the external shaft 130. The fixing mechanism includes a clamping member 210 slidably connected to the inside of the sliding groove 140, a rotating disk 220 clamped on the clamping member 210, a screw 230 connected to the bottom end of the rotating disk 220, and a threaded sleeve 240 threadedly connected to the screw 230. There are two parts 210, and the two snap-fit ​​parts 210 are combined into a rectangular ring. The locking mechanism includes an offset part 310 inserted in the middle of the rotating shaft 120, a locking head 320 connected to the outer end of the offset part 310 and extending into the interior of the sliding groove 140, a sliding head 340 abutting against the locking head 320, a connecting rod 350 connected to the outer end of the sliding head 340, and an anti-slide plate 360 ​​connected to the outer end of the connecting rod 350. A return spring 330 is provided between the offset part 310 and the locking head 320. The number of the offset parts 310 is two symmetrically arranged groups. The length of the anti-slide plate 360 ​​is equal to the length of the sliding groove 140, and the top of the anti-slide plate 360 ​​abuts against the bottom of the snap-fit ​​part 210.

[0024] Specifically, the anti-slide plate 360 ​​is disposed inside the sliding groove 140 and connected to the sliding head 340 at its bottom. When the anti-slide plate 360 ​​is pressed downward by the clamping member 210, the sliding head 340 will squeeze the position of the offset member 310, thereby pushing the locking head 320 at the front end to press against the screw rod 230 to lock the screw rod 230, thereby preventing the clamping member 210 from loosening, thereby ensuring the stability of the connection between the circumscribed shaft 130 and the rotating shaft 120.

[0025] The rotating shaft 120 is connected to the circumscribed shaft 130 so that the force is evenly distributed on the rotating shaft 120 and the circumscribed shaft 130 when the bevel gear 110 rotates, thereby avoiding the problem of structural disconnection and improving the practicality of the device.

[0026] The working principle and usage process of the present invention are as follows: first, the rotating shaft 120 is inserted into the external shaft 130, and the clamping piece 210 is inserted into the sliding groove 140 through the opening on the external shaft 130, and after being inserted into place, it is rotated ninety degrees so that the two clamping pieces 210 are opposite to each other, and the rotating disk 220 is used to drive the screw 230 to rotate and be threadedly connected with the threaded sleeve 240. At this time, the clamping piece 210 is slid toward the inner side of the external shaft 130 so that the position of the external shaft 130 is restricted by the clamping piece 210. Then, the rotating disk 220 is continuously rotated to make 21 slide inward until the rotating disk 220 presses the anti-slide plate 360 ​​toward the inside until it cannot move. At this time, the locking head 320 will jam the screw 230 so that it cannot rotate. The installation is completed and it can be used. Finally, the device can be maintained regularly to prevent rust.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
