Description
Technical field
The utility model relates to a kind of garden instrument, specifically is a kind of branches of tall trees pruner.
Background technology
The branches of tall trees pruner is a kind of in the garden instrument; Mainly be used for to trees particularly the high-altitude trees prune; Usually when utilizing the branches of tall trees pruner to prune; Often need to regulate the expansion link structure of branches of tall trees pruner,, thereby make the branches of tall trees pruner adapt to the pruning of differing heights so that change the bar minister degree of branches of tall trees pruner.
At present; The expansion link structure operated by rotary motion of branches of tall trees pruner between the preceding mobile jib of branches of tall trees pruner and back mobile jib, the expansion link structure of this branches of tall trees pruner comprise two ends be respectively applied for the expansion link of mobile jib adjustable side and mobile jib adjustable side, back before the suit, be set in before blocked shot, the lock sleeve that is used to lock and bottom in mobile jib adjustable side and the mobile jib adjustable side, back be fixedly connected with the card button of being with the arch spring leaf.The two ends of said expansion link offer hole clipping respectively, and the two ends end face of said expansion link also offers draw-in groove respectively, the adjustable distance of the expansion link structure that is the branches of tall trees pruner in the draw-in groove and the distance between the hole clipping of the same end of expansion link.Said blocked shot offers mounting groove, is fixedly connected with the bottom spring sheet that is evagination on the said mounting groove.The adjustable side of preceding mobile jib offers locating hole respectively with the adjustable side of back mobile jib in addition.
During assembling; Elder generation's suit two blocked shots; Before suit; The arch spring leaf that will block button bottom earlier places the mounting groove place of blocked shot and the arch spring leaf is pressed on the bottom spring sheet, before subsequently blocked shot slowly being packed in the adjustable side of the adjustable side of mobile jib or back mobile jib, and the locating hole of mobile jib or back mobile jib and block button some stretches out outside the locating hole until the card button that places blocked shot mounting groove place is connected to fully before.The adjustable side of preceding mobile jib and the adjustable side of back mobile jib all overlap load onto blocked shot after; And then the adjustable side of preceding mobile jib or the adjustable side of back mobile jib are slowly packed in the end of expansion link; This moment since the card button some stretch out before outside the locating hole of mobile jib or back mobile jib, it is just can clamping spacing on the draw-in groove of expansion link end then to block button.After the adjustable side of the adjustable side of mobile jib and back mobile jib all is sleeved on the end of expansion link before treating, put lock sleeve again, finally accomplish the assembling of the expansion link structure of branches of tall trees pruner.
The expansion link structure Design principle of above branches of tall trees pruner is to utilize bottom spring sheet and arch spring leaf, when needs are regulated the length of branches of tall trees pruner bar portion, unclamps lock sleeve; Push the card button, the moving telescopic bar, clamping is spacing in the draw-in groove or hole clipping of expansion link on request to make the card button; Thereby realize the length adjustment of branches of tall trees pruner bar portion; But in practical operation,, be difficult to block button and press because bottom spring sheet and arch spring leaf elasticity are little; Pushing the card button like effort then probably causes whole bottom spring sheet and arch spring leaf to lose efficacy; Add the bottom that the bottom spring sheet is fixedly connected in the mounting groove of blocked shot, the arch spring leaf is fixedly connected on card button, the replacing of then difficult realization bottom spring sheet and arch spring leaf, the scrapping of expansion link structure that can only cause whole branches of tall trees pruner.So the service life of the expansion link structure of the branches of tall trees pruner of the above structure of employing is shorter, operation is relatively more difficult when regulating.In addition, adopt the expansion link structure of the branches of tall trees pruner of above structure need offer mounting groove, also need fixed installation bottom spring sheet in mounting groove, and bottom spring sheet and arch spring leaf also need bending and molding, and the manufacturing process program is more, making is cumbersome.
The utility model content
The technical problem that the utility model will solve is the branches of tall trees pruner easy to operate when a kind of expansion link structure long service life, adjusting are provided, that the parts production process is few, the parts making is fairly simple.
For solving the problems of the technologies described above; The utility model adopts a kind of like this branches of tall trees pruner; It comprises the preceding mobile jib that has locating hole and back mobile jib, the expansion link structure between preceding mobile jib and back mobile jib; Said expansion link structure comprise be sleeved on before blocked shot, the two ends of mobile jib and mobile jib end, back be respectively applied for mobile jib and mobile jib end, back before the suit expansion link, be used to lock the lock sleeve of expansion link end; Said expansion link center line along its length is arranged with a plurality of hole clippings, and the card button that is used for locating hole and hole clipping clamping is equipped with in the inner of said blocked shot, is equipped with back-moving spring between the support portion of said card button and blocked shot.
Said hole clipping is four, and on the sidewall that wherein two are located at expansion link, two other is located on the end face of expansion link and forms draw-in groove.
The top of said card button is provided with the inclined plane.
After adopting above structure, the utility model compared with prior art has the following advantages: because the card button that is used for locating hole and hole clipping clamping is equipped with in the inner of said blocked shot; Be provided with back-moving spring between the support portion of said card button and blocked shot; And back-moving spring elasticity is big, makes to push the card button and become simple, has made things convenient for the operation of user in adjustment process; And back-moving spring only places between the support portion of card button and blocked shot; That is to say that back-moving spring is not to be fixedly connected with the card button, the replacing of back-moving spring becomes simply, convenience so make, and has prolonged the service life of expansion link structure.Back-moving spring can directly be bought in addition, and is very convenient, and the price material benefit, compared with prior art, save the production process of back-moving spring, made things convenient for the making of expansion link structure.
As improvement, said hole clipping is four, and on the sidewall that wherein two are located at expansion link, two other is located on the end face of expansion link and forms draw-in groove, has made full use of the length of expansion link, makes the adjusting length of branches of tall trees pruner obtain optimum control.
As further improvement, the top of said card button is provided with the inclined plane, is convenient to the hole clipping clamping on card button and the expansion link.
