[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] Example 1 This application discloses an electric pick for stripping exterior walls. (See also...) Figure 1 The electric pick includes a pick housing 1, a clamping head 2 slidably arranged at the front end of the pick housing 1, a pick head 3 mounted on the clamping head 2, and a drive mechanism mounted on the pick housing 1 and driving the pick head 3 to rotate at high speed. The front end of the pick housing 1 has a support section 11 for the operator to hold, and the rear end of the pick housing 1 has a handle section 12 for the operator to hold. When the operator is operating the electric pick, they can hold the handle with one hand and support themselves with the support section 11 with the other hand, making the operation of the electric pick more stable during operation.

[0032] Reference Figure 1 The electric hammer housing 1 has a mounting section 13 at the front end of the support section 11, and a splash guard 14 is detachably mounted on the outside of the mounting section 13. The outer surface of the mounting section 13 is cylindrical, and the splash guard 14 is a square baffle. The middle of the splash guard 14 has a mounting sleeve 141 that slides onto the outer surface of the mounting section 13. The mounting sleeve 141 extends outward from the rear end of the mounting section 13, and the extension length of the mounting sleeve 141 is not less than three times the thickness of the splash guard 14 and not greater than the length of the mounting section 13.

[0033] Reference Figure 1 and Figure 2The outer surface of the arrangement part 13 is provided with guide ridges 131 along its length. There are two guide ridges 131, and they are arranged symmetrically around the circumference. In this embodiment, the guide ridges 131 are strip-shaped protrusions with a rectangular cross-section. The mounting sleeve 141 is provided with guide grooves 1411 for sliding the guide ridges 131. The guide grooves 1411 on the mounting sleeve 141 correspond one-to-one with the guide ridges 131. The cooperation between the guide grooves 1411 and the guide ridges 131 makes it less likely for the mounting sleeve 141 to deflect during sliding installation into the arrangement part 13.

[0034] Reference Figure 1 and Figure 3 When the mounting sleeve 141 is slidably installed into the arrangement part 13, in order to reduce the probability that the mounting sleeve 141 will slide excessively beyond the arrangement part 13 and slide into the inner side of the electric hammer housing 1, the arrangement part 13 is provided with a limiting protrusion 132 for the mounting sleeve 141 to abut against at one end near the support part 11.

[0035] Reference Figure 2 The arrangement section 13 has a mounting groove 133, and a ball spring plunger 134 is disposed within the mounting groove 133. The ball spring plunger 134 includes a plunger housing 1341, a plunger ball 1342 installed within the plunger housing 1341, and a plunger spring 1343 installed inside the plunger housing 1341 and cooperating with the plunger ball 1342. The plunger housing 1341 is embedded within the mounting groove 133, and the plunger ball 1342 protrudes from the mounting groove 133. In this embodiment, there are two mounting grooves 133 arranged circumferentially symmetrically in the arrangement section 13, and the ball spring plungers 134 are arranged one-to-one within each mounting groove 133. The inner surface of the mounting sleeve 141 is provided with a snap-fit ​​groove 1412 for engaging the plunger ball 1342 of the ball spring plunger 134, and the snap-fit ​​groove 1412 is arranged one-to-one with the mounting groove 133 of the arrangement section 13. During the sliding installation of the mounting sleeve 141 of the splash guard 14 into the arrangement part 13, the plunger ball 1342 is pressed into the plunger housing 1341 so that the end of the mounting sleeve 141 can slide in the arrangement part 13. When the end of the mounting sleeve 141 abuts against the limiting protrusion ring 132, the snap-fit ​​groove 1412 on the mounting sleeve 141 coincides with the mounting groove 133 of the arrangement part 13. At this time, the plunger ball 1342 pops out and snaps into the snap-fit ​​groove 1412, thereby fixing the position of the mounting sleeve 141.

[0036] Reference Figure 3 and Figure 4A square splash guard 14 has a viewing slot 142 at the center of its upper edge, and a transparent baffle 143 is provided in the viewing slot 142. Both the viewing slot 142 and the transparent baffle 143 are square. The splash guard 14 has sliding grooves 1421 on both sides of the viewing slot 142, and the transparent baffle 143 has sliding protrusions 1431 that cooperate with the sliding grooves 1421. These sliding protrusions 1431 are strip-shaped protrusions with a rectangular cross-section. When an operator uses an electric pickaxe, they can observe the work situation through the transparent baffle 143 of the viewing slot 142.

[0037] Reference Figure 4 A locking piece 1432, which is square in shape, is provided on the bottom side of the transparent baffle 143. A locking groove 1433 is formed on the side of the locking piece 1432, and a first magnetic block 1434 is disposed within the locking groove 1433. A locking slot 144, which is square in shape, is formed at the lower edge of the visible slot 142 for inserting the locking piece 1432. A first slot 1441 is formed on the side wall of the locking slot 144, and a second magnetic block 1442, which engages with the first magnetic block 1434, is disposed within the first slot 1441.

[0038] Combination Figures 1 to 4 The implementation principle of an electric pick for exterior wall stripping according to an embodiment of this application is as follows: When the operator uses the electric pick to strip the exterior wall, the splash guard 14 is first slidably arranged on the arrangement part 13 along the guide protrusion 131 via the guide groove 1411. At this time, the splash guard 14 can be fixed on the arrangement part 13 by the ball spring plunger 134. During the operation, the splash guard 14 can block flying objects and protect the operator. At the same time, the operator can observe the operation through the transparent baffle 143 provided on the splash guard 14.

[0039] Example 2 The electric pick in this embodiment is the same as that in embodiment 1, except that the locking structure between the mounting sleeve 141 on the splash guard 14 and the arrangement part 13 of the electric pick housing 1 is different from that in embodiment 1.

[0040] Reference Figure 5 and Figure 6In this embodiment, the outer surface of the arrangement part 13 is provided with guide ridges 131 along its length. There are two guide ridges 131, and they are arranged symmetrically around the circumference. The mounting sleeve 141 is provided with guide grooves 1411 for sliding the guide ridges 131, and the guide grooves 1411 on the mounting sleeve 141 correspond one-to-one with the guide ridges 131. To ensure accurate installation of the splash guard 14, the arrangement part 13 is provided with a limiting ring 132 around its end near the support part 11 for the mounting sleeve 141 to abut against.

[0041] Reference Figure 5 and Figure 6 The outer surface of the arrangement part 13 is provided with a locking hole 135, and the mounting sleeve 141 is provided with a locking bolt 1413 that is threaded through the inner and outer surfaces and corresponds to the locking hole 135. When the end of the mounting sleeve 141 abuts against the limiting protrusion ring 132, the locking bolt 1413 and the locking hole 135 are aligned, and the splash guard 14 is firmly locked onto the arrangement part 13 by the locking hole 135 and the bolt.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
