The push switch 60 is selectively latched or released relative to the guiding rod 30 to urge the moving member 50 to the first position. Acting with the second position; the push switch 60 includes an engaging member 61 pivotally disposed on the pivots 52 via a coupling pin 63, and a pressing member 62 for driving the engaging member 61 to swing, the bottom side of the engaging member 61 A biting tooth 611 is provided for engaging the tooth portion 31 of the guiding rod 30, and a top side of the engaging member 61 has a non-circular protrusion 612, which is coupled with the engaging groove 621 of the pressing member 62, and the engaging member 61 and the pressing member 62 are also stably locked by a fixing screw 65. In addition, the bottom surface of the pressing member 62 has a flange 622, so that one end of the elastic member 64 is sleeved on the flange 622, and the other end is accommodated. The hole 54 of the moving member 50 causes the engaging member 61 to be normally locked to the guiding rod 30, and for the operation of the anti-slip effect, the pressing portion 62 can be provided with embossing on the top surface; when a force is applied to the pressing member 62, which can cause the engaging member 61 to be yawed relative to the moving member 50 centering on the engaging pin 63, so that Latching member 61 is no longer engaged in the guide bar 30, this way, i.e., the pressing member 62 can bring the moving member 50 moves along the long groove 13 is generated.

其中，於凸緣622之側邊設有兩翼部623，以當按壓件62與嚙合件61結合時，兩翼部623恰套設於突部612之兩側，以加強穩固結合效果。Two wings 623 are disposed on the side of the flange 622. When the pressing member 62 is coupled with the engaging member 61, the two wings 623 are sleeved on both sides of the protrusion 612 to enhance the stable bonding effect.

一固定塊17，係設置於第一殼體11與第二殼體12之間，並鄰近於手柄10之第二端102，固定塊17之兩側係分別透過一鎖固元件18與第一殼體11、第二殼體12固定之，此外，固定塊17具有一第一孔171，以供導引桿30之卡塊32插設結合，俾使得導引桿30設置於結合塊16與固定塊17之間，且無法相對固定塊17與結合塊16產生旋轉。A fixing block 17 is disposed between the first housing 11 and the second housing 12 and adjacent to the second end 102 of the handle 10. The two sides of the fixing block 17 respectively pass through a locking component 18 and the first The housing 11 and the second housing 12 are fixed. Further, the fixing block 17 has a first hole 171 for inserting and engaging the block 32 of the guiding rod 30, so that the guiding rod 30 is disposed on the coupling block 16 and There is no rotation between the fixed blocks 17 and the fixed blocks 17 and the joint blocks 16.

一彈簧70，其一端頂持於移動件50之止擋壁55，另一端則抵接於結合塊16，用以促使移動件50朝向第二位置，而彈簧70可套設於一圓桿80，圓桿80係平行於導引桿30，其一端固定於結合塊16，另一端則穿設過穿槽53以結合固定於固定塊17，較佳的是結合塊16與固定塊17各具有一凹孔或凹槽以供圓桿80之兩端結合固定之。A spring 70 has one end supported by the stopping wall 55 of the moving member 50, and the other end abuts against the coupling block 16 for urging the moving member 50 toward the second position, and the spring 70 can be sleeved on a round rod 80. The round bar 80 is parallel to the guiding rod 30, and one end thereof is fixed to the coupling block 16, and the other end is inserted through the through slot 53 to be fixedly coupled to the fixing block 17. Preferably, the bonding block 16 and the fixing block 17 each have a A recess or groove is provided for the two ends of the round bar 80 to be fixedly coupled.

如圖4、圖5所示，係為移動件50位於第一位置上，俾使得帶體20相對於圓柱狀之物體100處在鬆弛狀態，帶體20則能有間隙地圍繞所圈設之物體100，其中，按壓式開關60之嚙合件61之咬合齒611嚙合於導引桿30之齒部31，以形成鎖定狀態。As shown in FIG. 4 and FIG. 5, the moving member 50 is located at the first position, so that the belt body 20 is in a relaxed state with respect to the cylindrical object 100, and the belt body 20 can be surrounded by the gap. The object 100 in which the engaging teeth 611 of the engaging members 61 of the push switch 60 are engaged with the tooth portions 31 of the guide rod 30 to form a locked state.

如圖6至圖8所示，當使用者握持於手柄10，並利用大拇指對按壓式開關60之按壓件62施力按壓，致使嚙合件61相對移動件50樞擺，而能使嚙合件61之咬合齒611脫離於齒部31，如此使用者操控按壓式開關60往圖式下方移動，以帶動移動件50於導引桿30產生下移之動作，俾使移動件50從第一位置朝第二位置動作。As shown in FIG. 6 to FIG. 8 , when the user holds the handle 10 and presses the pressing member 62 of the push switch 60 with a thumb, the engaging member 61 pivots relative to the moving member 50 to enable meshing. The engaging teeth 611 of the member 61 are disengaged from the tooth portion 31, so that the user controls the push-type switch 60 to move downwardly to move the moving member 50 to the lowering of the guiding rod 30, so that the moving member 50 is moved from the first The position moves toward the second position.

其中，當咬合齒611脫離於齒部31時，移動件50受能到彈簧70之彈力釋放，而輔助移動件50之下移動作，使得移動件50輕易地動作到第二位置上，此時，帶體20隨著移動件50之下移，而能從鬆弛狀態逐漸地形成緊固狀態並將物體100圈繞住，而牢固地繞設於物體100之周緣，當帶體20已經緊固於物體100後，使用者可不再按壓於按壓件62，以使嚙合件61再次卡鎖於導引桿30形成定位狀態(如圖8)，以便提供使用者利用手柄10側向擺動，以單向地驅轉物體100使其產生旋動，以順利地拆離物體100，以便對圓柱狀之機油濾清器進行維修之作業。Wherein, when the engaging teeth 611 are disengaged from the tooth portion 31, the moving member 50 is released to the elastic force of the spring 70, and the auxiliary moving member 50 is moved downward, so that the moving member 50 is easily moved to the second position. The belt body 20 can gradually form a fastening state from the relaxed state and wrap the object 100 around the moving member 50, and is firmly wound around the circumference of the object 100, when the belt body 20 has been fastened. After the object 100, the user can no longer press the pressing member 62, so that the engaging member 61 is locked again to the guiding rod 30 to form a positioning state (as shown in FIG. 8), so as to provide the user to swing laterally by the handle 10. The object 100 is driven to the ground to cause it to be rotated to smoothly detach the object 100 for maintenance work on the cylindrical oil filter.

由於，按壓式開關60於操作過程中，可控制嚙合件61相對於導引桿30之鎖定或釋放，以便帶動移動件50產生位移，致使可控制帶體20之環圈大小，而使帶體20能夠調整之適當尺寸以對應於物體100，提供使用者方便使用。Because the push switch 60 can control the locking or releasing of the engaging member 61 relative to the guiding rod 30 during operation, so as to drive the moving member 50 to generate displacement, so that the ring size of the belt body 20 can be controlled, and the belt body is controlled. 20 can be adjusted to the appropriate size to correspond to the object 100, providing the user with ease of use.

再者，本發明可提供使用者單手操作於按壓式開關60，以便相對導引桿30卡鎖或釋放，同時能帶動移動件50於第一位置與第二位置之間動作，其操作上相當簡易而方便。Furthermore, the present invention can provide a user to operate the push switch 60 with one hand so as to be locked or released relative to the guiding rod 30, and can simultaneously move the moving member 50 between the first position and the second position, and the operation thereof is performed. Quite simple and convenient.

雖然本發明是以一個最佳實施例作說明，精於此技藝者能在不脫離本發明精神與範疇下作各種不同形式的改變。以上所舉實施例僅用以說明本發明而已，非用以限制本發明之範圍。舉凡不違本發明精神所從事的種種修改或改變，俱屬本發明申請專利範圍。While the invention has been described in terms of a preferred embodiment, the various embodiments may The above embodiments are merely illustrative of the invention and are not intended to limit the scope of the invention.
