[0063] In some embodiments, please refer to Figures 10 to 18 , multiple cutting parts are evenly distributed along the length direction of the main shaft 230, and each cutting part is arranged in a second chamber separated by the second partition 201. In other words, the cutting components 240 are divided into two groups, upper and lower, with the main shaft 230 as the dividing line, and the two groups of cutting components 240 are connected by a connecting plate 204, and each group of cutting components 240 is arranged with multiple cutting parts along the length direction of the main shaft 230. The cross-sectional shape of the second partition 201 is rectangular, and each second partition 201 is parallel, equidistant and perpendicular to the length direction of the main shaft 230.

[0064] Specifically, please refer to Figures 13 to 15 The first rack 231 is disposed on the surface of the middle section of the main shaft 230. The first racks 231 are identical and their length direction is consistent with the length direction of the main shaft 230. The two ends of the first racks 231 are close to the surface of the second shell 210 but do not contact the surface of the second shell 210. The second partition 201 can enclose a rectangular second chamber. Each second chamber is provided with four U-shaped grooves 241, a reciprocating element 242, a spring element 243 and a connecting rod 344. The length direction of the U-shaped groove 241 is perpendicular to the length direction of the main shaft 230. The overall shape of the reciprocating element 242 is a rectangular parallelepiped.

In other words, the positional relationship between the limit plate 248, the reciprocating element 242 and the spring element 243 in the two chopping components of the chopping assembly 240 is different, please refer to Fig.13 The reciprocating element 242 and the spring element 243 in the chopped component on the upper side of the main shaft 230 are on both sides of the limit plate 248, and the reciprocating element 242 and the spring element 243 in the chopped component on the lower side of the main shaft 230 are on the same side of the limit plate 1148; the initial state of the spring element 243 in the chopped component on the upper side of the main shaft 230 is a tensile state; the initial state of the spring element 243 in the chopped component on the lower side of the main shaft 230 is a compressive state; the reciprocating elements 242 in the two chopped components are initially tightly fitted with the limit plate 248 due to the action of the spring element 243.

[0066] In other embodiments, flexible materials (such as rubber pads) may be added to the two opposite sides of the limit plate 248 and the reciprocating element 242 to reduce the force and sound of the collision between the limit plate 248 and the reciprocating element 242 to achieve a buffering effect.

[0067] In some embodiments, please refer to Figure 4 There are four displacement components 250, which are respectively located at the four corners of the chopping head 200 close to the surface to be chopped. Fig.11 , 12and 16, the surfaces of the second housing 210 corresponding to the four shifting assemblies 250 are respectively concave inward to form an arch groove 252, and the directional wheels 251 are respectively fixed to the bottom of the arch groove 252 through retractable connectors 253; when the directional wheels 251 are in contact with the surface to be chopped and the connector 253 is not under pressure, the chopping blade 245 does not touch the surface to be chopped; when the connector 253 is compressed and shrunk, the chopping blade 245 chops into the surface to be chopped. Specifically, the shifting assemblies 250 are all located on the two surfaces on the front side of the second housing 210, the directional wheels 251 are connected to the front end of the connector 253 and can be directional and rotatable, and the rear end of the connector 253 is fixed to the bottom of the arch groove 252 through a nut. When the connector 253 is under pressure, it will shrink and deform to a certain extent, and it will recover after the pressure is removed. It should be noted that there needs to be a certain friction between the directional wheel 251 of the displacement assembly 250 and the surface to be cut, so as to ensure that the device only moves in a directional direction without deviation in other directions when in operation.

[0068] In some embodiments, please refer to Fig.19 The body 310 is also provided with a handle 330 and a verticality meter panel 340, which are disposed on a surface adjacent to the surface of the body 310 where the slot 320 is located. In this embodiment, the cross-sectional shape of the body 310 is rectangular, and a slot 320 is provided on the right side of the body 310. The slot 320 is vertically through-through and has an open upper end and a closed lower end. The handle 330 and the verticality meter panel 340 are disposed on the back of the body 310.

[0069] When the clamping strip 260 is inserted into the clamping slot 320, the chopped and formed part and the auxiliary displacement part 300 always keep close contact, and the clamping strip 260 can move up and down in the clamping slot 320, so that the chopped and formed part and the auxiliary displacement part 300 of the equipment move relative to each other; with the expansion and contraction deformation of the connecting member 253 of the displacement assembly, the clamping strip 260 can shift forward and backward in the clamping slot 320. Of course, the front of the body 310 should have a certain degree of roughness to ensure that the auxiliary displacement part 300 and the surface to be chopped remain relatively stable during the use of the equipment by the construction personnel, and no accidental shift or dislocation occurs.

[0070] In addition, in order to reduce the overall weight of the equipment and facilitate operation by construction personnel, the equipment's outer shell (including the first outer shell 110, the second outer shell 210 and the third outer shell), partitions, body 310 and other enclosure parts can be made of ABS plastic, and the equipment's bearing seat, transmission shaft 220, bearings 221, gears, main shaft 230, chopping assembly 240 and other parts that play a mechanical transmission and chopping role can be made of lightweight alloy steel.

[0071] The present invention also provides a method for forming a textured surface layer of artificial stone on a building exterior wall, which uses the above-mentioned equipment for forming a textured surface layer of artificial stone on a building exterior wall, and comprises the following steps:

[0072] Step 1: Turn on the switch 140 and check the power status of the device. If the power indicator light 170 shows that the power is low, charging is required to ensure that the device has sufficient power.

[0073] Step 2: Remove the protective cover 215, check whether the shifting assembly 250, the chopping assembly 240 and other components are intact, and then press the control button 150 to check whether the chopping blade 245 operates normally.

[0074] Step 3: Perform trial chiseling at a local position of the surface to be chiseled, so that the chiseling blade 245 can normally and smoothly chisel out a texture of a certain depth on the artificial stone surface layer.

[0075] Step 4: Place the auxiliary displacement part 300 at a corner of the surface to be chopped, such as the upper right corner, so that the rough surface of the body 310 fits with the surface layer to be chopped. The slot 320 is located on the right side of the auxiliary displacement part 300 with the open end facing upward. Adjust the auxiliary displacement part 300 with the help of the verticality instrument panel 340 to keep the auxiliary displacement part 300 in a vertical state.

[0076] Step 5: Hold the handle 330 of the auxiliary displacement part 300 with your left hand and press the auxiliary displacement part 300 against the surface to be cut to ensure that the auxiliary displacement part 300 does not shift; hold the handle 100 of the cutting and forming part with your right hand, insert the clip 260 on the side of the cutting head 200 from the open end of the slot 320 of the auxiliary displacement part 300, and make the directional wheels 251 of all the displacement components 250 of the cutting and forming part contact with the surface to be cut.

[0077] Step 6: Press and hold the control button 150 to put the chopping blade 245 in a reciprocating state, and apply pressure perpendicular to the surface to be chop to the chopping forming portion, so that the connecting parts 253 of each shifting assembly 250 are compressed and contracted at the same time, and each chopping blade 245 chops a texture of the same depth on the surface to be chop.

[0078] Step 7: Release the control button 150, remove the pressure applied to the chopping and cutting forming part, allow the connecting parts 253 of each shifting assembly 250 to restore their deformation, and then move the chopping and cutting forming part along the slot 320 to the next position, such as moving downward a certain distance, to ensure that the chopping and cutting blade 245 covers a certain existing texture.

[0079] Step 8: Repeat steps 6 to 7 until the clip 260 abuts against the closed end of the lower portion of the slot 320 , then move the auxiliary displacement portion 300 downward and move the clip 260 to the open end of the upper portion of the slot 320 , without allowing the clip 260 to slip out of the slot 320 .

[0080] Step 9: Repeat steps 6 to 8 until the device reaches the lower boundary of the surface to be cut.

[0081] Step 10: Reposition the device to the upper boundary of the surface to be cut and offset the device to the left by a certain distance compared to the previous position, and use the verticality instrument panel 340 again to ensure that the entire device is in a vertical state.

[0082] Step 11: Repeat steps 6 to 10, from top to bottom and from right to left, until the texture forming work of the surface to be chopped and cut is completed.

[0083] It should be noted that in step 10, if there is no clear design requirement for the texture spacing of the artificial stone surface layer, the distance of the left shift of the equipment can be determined by intuitive judgment to ensure that the formed texture is roughly uniform; if there is a clear design requirement for the texture spacing of the artificial stone surface layer, markings can be made with the help of tools such as rulers and charcoal pencils to assist in determining the positioning of the left shift of the equipment.

[0084] In addition, in the actual construction process of the project, if the area of ​​the artificial stone surface layer of the building exterior wall to be chopped is large or there are local problems such as columns, waistlines, door and window openings, etc., the surface layer to be chopped can be planned into several partitions according to the specific situation, and then the construction work can be carried out in each partition in sequence or simultaneously according to the above steps.
