DETAILED DESCRIPTION

[0025] In order to conveniently solve the problem that the existing louver mill head is troublesome when replacing the mill head, needs to disassemble multiple components, increases operation time and labor intensity, the utility model discloses a louver mill head with a movable handle. The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment. Obviously, the described embodiment is only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1-5 The utility model provides a louver mill head with a movable handle, which comprises a louver mill head body 1, a connecting rod 2 is arranged on one side of the louver mill head body 1, a connecting seat plate 313 is arranged on the connecting end of the louver mill head body 1, and guide insertion slots 314 for the sliding of positioning plugboards 312 are formed on the two sides of the connecting seat plate 313.

[0027] The connecting rod 2 and the connecting end of the louver mill head body 1 are provided with a clamping assembly 3, the clamping assembly 3 comprises a containing cavity 301 in the connecting rod 2, an abutment rod 302 is slidably connected in the containing cavity 301, and a baffle 303 is arranged on the outer periphery of the abutment rod 302 in the containing cavity 301. A reset spring 304 is arranged on the outer periphery of the abutment rod 302, and the reset spring 304 is located directly above the baffle 303. An shaft pressing plate 305 is arranged on the upper part of the abutment rod 302, the shaft pressing plate 305 and the abutment rod 302 are connected through a guide support plate 306, the shaft pressing plate 305 and the abutment rod 302 are connected through a guide support plate 306, a rotating plate is rotatably connected to the outer periphery of the shaft pressing plate 305, and an inner thread groove 3051 is formed in the lower inner wall side of the rotating plate.

[0028] The connecting rod 2 is provided with guide grooves 307 on both sides of the accommodating cavity 301 for linear movement of the guide support plate 306, and the connecting rod 2 is provided with an external thread groove 201 at the lower part of the guide groove 307 to cooperate with the internal thread groove 3051.

[0029] The accommodating cavity 301 has inner grooves 308 on both sides of the lower part of the baffle 303. A rotating stop bar 310 is provided in the inner groove 308 through a torsion spring shaft 309. The side of the rotating stop bar 310 away from the torsion spring shaft 309 is connected to a positioning insert plate 312 through a ball bearing 311.

[0030] The connecting end of the flap wheel grinding head body 1 and the connecting rod 2 is provided with a concave groove 101 that cooperates with the connecting seat plate 313, and the two sides of the concave groove 101 are provided with positioning grooves 102 that cooperate with the positioning insert plate 312.

[0031] The flap wheel grinding head body 1 is connected to the connecting rod 2 via the locking assembly 3.

[0032] The working principle of the flap wheel grinding head provided by this utility model is as follows: the connecting rod 2 is brought close to the side of the flap wheel grinding head body 1, so that the connecting seat plate 313 on the connecting rod 2 is aligned with the concave groove 101 on the flap wheel grinding head body 1. At this time, the positioning insert plate 312 is located in the guide slot 314 and is in the initial position.

[0033] Pressing down the shaft pressure plate 305 causes the abutment rod 302 in the accommodating cavity 301 to move downward under force. The shaft pressure plate 305 drives the guide support plate 306 to slide linearly in the guide groove 307, squeezing the reset spring 304.

[0034] As the abutment rod 302 continues to advance, the rotating stop rod 310 is compressed and rotates around the torsion spring shaft 309, causing the positioning plate 312 to move closer to the positioning groove 102 under the action of the ball bearing 311.

[0035] After the positioning plate 312 is fully inserted into the positioning groove 102, the rotating plate on the outer periphery of the shaft pressure plate 305 is rotated. The internal thread groove 3051 of the rotating plate cooperates with the external thread groove 201 at the bottom of the connecting rod 2 to fix the position of the shaft pressure plate 305 and limit the positioning plate 312, thereby completing the initial fixation of the flap wheel grinding head body 1 and the connecting rod 2.

[0036] During disassembly, rotate the rotating plate on the side of the shaft pressure plate 305 in the opposite direction and unscrew the rotating plate from the external thread groove 201. At this time, the return spring 304 elastically returns and resets the abutment rod 302. Then, the rotating stop rod 310 returns to its original position under the elastic force of the torsion spring shaft 309, and the positioning insert plate 312 moves out of the positioning groove 102. Then, the connection between the positioning insert plate 312 and the flap wheel grinding head body 1 is released. At this time, the flap wheel grinding head body 1 and the connecting rod 2 can be removed respectively.

[0037] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
