[0029] The following combines the attached Figure 1-6 With the embodiments, the present utility model will be further described in detail.

[0030] Embodiment 1

[0031] A grinder for quickly replacing the grinding head includes a lower body 1 for storing solid particulate matter and an upper body 2 for providing power. The upper body 2 is detachably installed on the lower body 1. The lower body 1 includes a lower housing 11, a grinding head 12 and a connecting rod 13. The grinding head 12 is fixedly connected to the connecting rod 13 and installed on the lower housing 11. The upper end of the connecting rod 13 extends out of the top of the lower housing 11 and forms a joint 131. A push-type locking switch 21 is installed on the upper body 2. When the upper body 2 is pressed, the locking switch 21 is locked or separated from the joint 131, and the upper body 2 can be quickly replaced from one lower body 1 to another lower body 1.

[0032] The upper body 2 includes an upper housing 22. The top of the lower housing 11 extends into the upper housing 22 and is joined and connected thereto. A gap 100 for providing a pressing space is provided between the upper housing 22 and the lower housing 11. Pressing the upper housing 22 makes it move towards the lower housing 11, thereby reducing the distance of the gap 100, realizing the locking or separation between the upper body 2 and the lower body 1. The gap 100 ensures that the two bodies can be joined together.

[0033] On the inner wall at the lower end of the upper housing 22, there are at least two first clamping grooves 221 which are circumferentially evenly distributed. On the outer wall at the upper end of the lower housing 11, there are at least two clamping blocks 111 which are circumferentially evenly distributed. All the clamping blocks 111 are vertically arranged. The lower housing 11 is clamped and connected to the first clamping grooves 221 of the upper housing 22 through the clamping blocks 111, so that the upper body 2 has better stability on the lower body 1 and will not radially shake.

[0034] The joint 131 is provided with a second clamping groove 132, and the second clamping groove 132 is an annular clamping groove. The lock switch 21 is provided with a claw 211. When the upper body 2 is pressed, the claw 211 is clamped or separated from the second clamping groove 132. The lock switch 21 on the upper body 2 can be connected with the joint 131 at multiple angles, which is convenient for the upper body 2 to be installed on the lower body 1.

[0035] A connecting seat 23 is also installed on the upper body 2, and the lock switch 21 is installed on the connecting seat 23. The upper end of the connecting rod 13 is fixed with an engaging part 133 that rotates synchronously with it. The connecting seat 23 and the engaging part 133 are engaged to form a radial limit. The power generated by the upper body 2 can be transmitted to the engaging part 133 through the connecting seat 23, so as to realize the stable output of power and ensure the stable operation of the grinding head 12 in the lower body 1.

[0036] The engaging part 133 is provided with an engaging groove 130. The inner wall of the engaging groove 130 is integrally formed with lower limiting blocks 134, and the number of the lower limiting blocks 134 is 4. The connecting seat 23 is provided with upper limiting blocks 233 with the same number as the lower limiting blocks 134. The upper limiting blocks 233 extend into the engaging part 133 and are in radial contact connection with the lower limiting blocks 134. When the connecting seat 23 rotates, the upper limiting blocks 233 on it will abut against the lower limiting blocks 134 of the engaging part 133, thereby driving the engaging part 133 to rotate.

[0037] The lower housing 11 is provided with a chamber 110 for placing granular materials. The top of the lower housing 11 is provided with a groove 112 which is communicated with the chamber 110 and is used for placing the engaging part 133. The connecting rod 13 passes through the groove 112 and is connected with the engaging part 133. The engaging part 133 has good stability on the lower housing 11 and will not shake easily.

[0038] The connecting rod 13, the joint 131 and the engaging part 133 are integrally formed. This connection method has high strength. The joint 131 is arranged at the center position of the engaging part 133, and the joint 131 and the connecting rod 13 are on the same axis, ensuring good stability of the rotation of the grinding head 12.

[0039] In this embodiment, the connecting seat 23 is a split type. The connecting seat 23 includes an upper seat body 231 and a lower seat body 232. A convex block 2311 protruding downward is fixed on the upper seat body 231. An installation groove 2312 is provided on the convex block 2311. The lock switch 21 is installed in the installation groove 2312 by a clamping method. The lower seat body 232 is sleeved on the convex block 2311, and the lower seat body 232 is radially limited on the convex block 2311. An upper limit block 233 is integrally formed on the lower seat body 232. An elastic reset member 234 is provided between the upper seat body 231 and the lower seat body 232. The elastic reset member 234 is a spring. The elastic reset member 234 facilitates the installation of the upper body 2 on the lower body 1 by pressing. At least two guide posts 235 are provided on the upper seat body 231. In this embodiment, the number of guide posts 235 is two. The guide posts 235 pass through the lower seat body 232 and are axially limited and connected by fasteners 236. The fasteners 236 are screws. The guide posts 235 play a guiding role and also axially limit the lower seat body 232 on the upper seat body 231. The upper seat body 231 can axially move a set distance towards the lower seat body 232.

[0040] The upper body 2 includes a battery 26, a motor 24, and a speed reducer 25. The battery 26 is connected to the motor 24 and provides electrical energy for it. The output end of the motor 24 is connected to the speed reducer 25. The speed reducer 25 is connected to the lock switch 21. The output end of the speed reducer 25 is connected to the upper seat body 231. The speed reducer 25 can drive the upper seat body 231 to rotate. The upper seat body 231 can drive the lower seat body 232 to rotate. The lower seat body 232 can drive the joint portion 133 to rotate.
