DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] A gear, as Figures 1 - 8 shown, includes a gear body 1 and a plurality of teeth 2 provided on the gear body 1. A plurality of mounting grooves 3 are formed on the side wall of the gear body 1. A connecting block 4 is detachably connected in the mounting groove 3 through a connecting member, and the connecting block 4 is fixedly connected to the tooth 2.

[0028] Furthermore, the connecting member includes a limiting groove 5 formed at the bottom of the mounting groove 3. An elastic block 6 is fixedly connected to the inner wall of the limiting groove 5. A limiting plate 7 for inserting into the limiting groove 5 is fixedly connected to the bottom of the connecting block 4. Card slots 8 for the elastic block 6 to snap into are formed on both sides of the limiting plate 7. Align the limiting plate 7 at the bottom of the connecting block 4 with the limiting groove 5 at the bottom of the mounting groove 3 and insert the limiting plate 7 into the limiting groove 5. During the process of inserting the limiting plate 7 into the limiting groove 5, the elastic block 6 will undergo elastic deformation under extrusion. When the position of the elastic block 6 corresponds to that of the card slot 8, the elastic block 6 returns to its original state and snaps into the card slot 8, thereby achieving the effect of fixing the limiting plate 7 in the limiting groove 5, and thus fixing the connecting block 4 in the mounting groove 3. Moreover, the elastic block 6 is an arc-shaped block and the card slot 8 is an arc-shaped groove, which is more convenient for the mutual connection and separation of the elastic block 6 and the card slot 8.

[0029] Further, a sliding groove 9 is formed in the inner wall of the installation groove 3 near its notch. A contact plate 10 for restricting the longitudinal movement of the connection block 4 is slidably connected in the sliding groove 9. A fixing block 11 for closing the notch of the installation groove 3 is fixedly connected to one side of the contact plate 10 close to the notch of the installation groove 3. A fixing component for fixing the contact plate 10 in the sliding groove 9 is provided on the gear body 1. After the connection block 4 is fixed in the installation groove 3, the contact plate 10 is pushed to slide towards the bottom of the sliding groove 9. Since the fixing block 11 is fixedly connected to the contact plate 10, the fixing block 11 will also move along with it. When the contact plate 10 contacts the bottom of the sliding groove 9, the contact plate 10 is fixed in the sliding groove 9 by using the fixing component. By the restriction of the contact plate 10, the longitudinal movement of the connection block 4 is avoided, and the stability of the connection block 4 fixed in the installation groove 3 is further enhanced.

[0030] Further, the fixing component includes a threaded hole formed in the gear body 1 and a positioning hole formed in the side wall of the contact plate 10. The threaded hole is in communication with the sliding groove 9 and a screw 12 is threadedly connected in the threaded hole. After the contact plate 10 is slid to contact the bottom of the sliding groove 9, the screw 12 is rotated until it is inserted into the positioning hole. After the screw 12 is loosened, the self-locking characteristic of the threaded connection between the screw 12 and the threaded hole is utilized to fix the position of the contact plate 10.

[0031] Further, a groove 13 is formed in the gear body 1, and the threaded hole is located at the bottom of the groove 13, so as to avoid the inconvenience in use caused by the screw 12 protruding from the surface of the gear body 1 after the contact plate 10 is fixed in the sliding groove 9 by using the screw 12.

[0032] Further, an elastic pad 14 is fixedly connected to one side of the contact plate 10 facing the bottom of the installation groove 3. After the connection block 4 is fixed in the installation groove 3, the contact plate 10 is pushed to drive the elastic pad 14 to move. After the elastic pad 14 abuts against the connection block 4, the elastic pad 14 will elastically deform and contract. After the contact plate 10 is fixed, the contracted elastic pad 14 can apply a force to the connection block 4 to tightly abut the connection block 4, thereby improving the stability of the connection block 4 installed in the installation groove 3.

[0033] The use of the present utility model is as follows:

[0034] Align the limiting plate 7 at the bottom of the connecting block 4 with the limiting groove 5 at the bottom of the installation groove 3 and insert the limiting plate 7 into the limiting groove 5. By the mutual clamping of the elastic block 6 and the clamping groove 8, the effect of fixing the connecting block 4 in the installation groove 3 is achieved, thereby realizing the mutual connection between the tooth 2 and the gear body 1. Then, push the abutting plate 10 to slide it towards the bottom side of the sliding groove 9, and the fixing block 11 and the elastic pad 14 will also move together. After sliding the abutting plate 10 until it contacts the bottom of the sliding groove 9, rotate the screw rod 12 until it is inserted into the positioning hole to fix the position of the abutting plate 10. When a certain tooth 2 needs to be replaced due to wear, the corresponding connecting block 4 can be removed from the installation groove 3 for replacement, which is simple and convenient, without the need to replace the entire gear, avoiding waste of resources.

[0035] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
