煩わしいばかりでなく能率をも低下する欠点があ
るものである。(b) Prior art and problems to be solved by the present invention Conventionally, there has been a device that connects the left and right brackets and the boss inserted between the brackets by inserting a pin into the boss. In order to adjust the gap between the bracket and the boss, this type of device provides an adjustment member by inserting a pin between the bracket and the boss on one side, and the boss is adjusted by the adjustment member and the bracket on the other side. This type of device consists of a fixing member for fixing the adjustment member in a state where it is clamped, but when the pin is connected to this type of device, the hole in the bracket, the hole in the boss, and the hole in the adjustment member are Since it is not possible to connect pins that do not match, it is necessary to match the holes, but this method has the disadvantage that it is not only extremely troublesome, but also reduces efficiency.
(ハ) 問題点を解決する為の手段
本考案は従来の考案に上記の様な欠点があつた
ので構造を簡単にすると共に作業の能率化を計つ
たものである。(c) Means for solving the problems The present invention aims to simplify the structure and improve the efficiency of work since the conventional devices had the above-mentioned drawbacks.
即ち、左右のブラケツトの間にボスを嵌合し、

のである。 That is, fit the boss between the left and right brackets,
Tapered holes are provided symmetrically in the left and right brackets and the boss, and tapered pins each having a flange head and a tapered body are fitted into these holes, and the flange is screwed onto the bracket. It has stopped.
(ニ) 実施例及び作用
本考案に関する実施の一例を示せば下記の通り
である。(d) Examples and effects An example of the implementation of the present invention is as follows.
図中１はボス。 1 in the diagram is the boss.
２，２は中間にボス１を挾んで左右に設けたブ
ラケツト。 2, 2 are brackets placed on the left and right with boss 1 in between.
３はボス１の左右両端から中央部に達して設け
た左右対称のテーパー状の穴。 3 is a symmetrical tapered hole provided from both left and right ends of the boss 1 to the center.
４はテーパー状の穴に合致させてブラケツトに
連設したテーパー状の穴。 4 is a tapered hole that matches the tapered hole and is connected to the bracket.
５はフランジの頭部ａとテーパー状の胴部ｂを
持つたテーパー状のピン。 5 is a tapered pin having a flange head a and a tapered body b.
６はテーパー状のピンのフランジの頭部ａをブ
ラケツト２，２に固定した止螺子である。 Reference numeral 6 designates a set screw which fixes the head a of the flange of the tapered pin to the brackets 2, 2.
７はバケツト、８はシリンダー、９はロツト、
１０はボスのアームである。 7 is Bucket, 8 is Cylinder, 9 is Lot,
10 is the boss's arm.
本考案は上記の様に構成されているのでピンの
結合を行なわんとする時は、ボスの穴３の一端を
一方のブラケツトの穴４に合致させ、之に左右対
称的に形成したテーパー状のピンの胴部ｂを嵌合
し、フランジを止螺子６によりブラケツト２に固
定すればボス１は一方のブラケツト２に正確に結
合されるから、上記と同じ様にボスの穴３の他端
を他方のブラケツト２の穴３に合致させ、之に左
右対称的に形成したテーパー状のピンの胴部６を
嵌合してフランジの頭部ａを止螺子６によりブラ
ケツト２に固定すれば、ボスは他方のブラケツト
に正確に結合されるものである。 Since the present invention is constructed as described above, when it is time to connect the pins, one end of the hole 3 of the boss is aligned with the hole 4 of one of the brackets, and a tapered shape formed symmetrically therebetween is used. If the body part b of the pin is fitted and the flange is fixed to the bracket 2 with the set screw 6, the boss 1 will be accurately connected to one bracket 2, so the other end of the hole 3 of the boss is aligned with the hole 3 of the other bracket 2, and the symmetrically formed tapered body 6 of the pin is fitted therein, and the head a of the flange is fixed to the bracket 2 with the set screw 6. The boss is precisely connected to the other bracket.
尚、本考案に於てはボスのピン穴３もブラケツ
トのピン穴４も共にテーパーに形成されているか
ら、例え両者の穴が合致していない状態でピンを
挿入してもテーパー状のピン穴は自然に合致する
から、ピンの結合に煩わしさがなく容易に行うこ
とが出来るものである。 In addition, in the present invention, both the pin hole 3 of the boss and the pin hole 4 of the bracket are formed in a tapered manner, so even if the pin is inserted when the two holes do not match, the tapered pin will not be inserted. Since the holes match naturally, the pins can be easily connected without any trouble.

するものである。(e) Effects of the invention This invention makes it easy to connect the boss and bracket by simply inserting a symmetrically formed tapered pin into the pin hole between the left and right brackets and the boss inserted into these brackets. However, this pin has an extremely simple structure because the head of the flange is fixed to the bracket with a set screw, and even if the pin holes of the bracket and boss are misaligned, the pin can be inserted easily. Since the pins can be connected while correcting the misalignment, the pins can be connected easily without any trouble, so it is very effective as a pin connecting device.
